Question about Coleman Heating & Cooling
It sound like your first stage sequencer is stuck in the 'on' position Shad. Usually the first stage is responsible for turning on the blower on low speed while energizing the first 5 kw of electric heat.
The problem you describe is typical of 'stuck' contacts within the sequencer.
No field service to the sequencer, replacement is necessary. Of course without actually seeing your furnace, this is just a resonably educated guess.

You should be seeing 120 volts to the igniter. Anything less requires either a replacement of the transformer, start relay or control module.

Small blower motor? Are you talking about the combustion blower if so then check your vents for blockage.. if the vents are blocked won't work... if it has a control board init it will give you a diagnostic code. Flashing light on the board... count the flashes and look up the fault on the chart in your owners manual ot on the furnace door..

Looks like 4 flashes might be high limit fault on this furnace. (I don't have a manual for this furnace, just searched online for the code meaning) Is the unit running flame at all? Is the unit running flame for a while then shutting flame off before desired temp is reached? Does the main air fan turn on to circulate air through your diffusers? Does it feel like the unit has much air flow out of the diffusers if the fan is running? Is your air filter clean? If it is infact your high limit switch, it is usually caused by not having enough airflow through the furnace and overheating occurs.
Hope this helped, let me know if I can assist you further :)

Typically you normally will have five wires controlling your furnace and airconditioning. R Y W G C. If you get some thermostat wire. Connect them like this---- red wire will go to R(this is your 24V to thermostat)----yellow wire will go Y(Y is your cooling)----white wire will go W(W is for heating)---green wire to G(green is your fan)---black can go to C(this is your common to supply 24Vto thermostat)
